UNITED sTA'rss JOHN O. BURT, OF MEMlI-IIS, TENNESSEE.

FUMIGATOR.

v Application filed October 12, 11926. Serial No. 141,140.

rhis invention relates to umigators and it is an object of the invention to provide a de ice of this hind constructed in a manner whereby the discharge of the fumes may be regulated.

It is also an object of the invention to provide a device of this kind providing'for the use of dii'ering fumigating materials.

The invention consists in the detailsy of construction and in the combination and arrangement of the several parts of my im proved iumigator whereby certain important advantages are attained and the device rendered simplen less expensive and otherwise more convenient and advantageous for use, as will be hereinafter more fully set forth. v n

The novel 'features oil my invention will hereinafter be detintely claimed.

In order that my invention may be the better understood. I will now proceed to describe the same with reference to the accompanying drawing, wherein Figure 1 is a longitudinal sectional View taken through a fumigator constructed in accordance with anembodiment of my invent-ion with certain of the parts in elevation;

Figure 2 is a view in elevation of the device as herein disclosed;

Figure 3 is a View in top structure as herein set forth;

Figure 4 is a sectional view taken sub stantially on the line 4 4 ot Figure 1.

As disclosed in the accompanying drawing, H denotes a supporting member adapt ed to be atxed at a desired location and which, as herein disclosed, comprises a cylindrical body 1v open at its top and provided at its opposite ends with the arms 2 with which suitable fastening members are adapted to co-operate.

My improved umigator is adapted to be placed within the cylindrical body 1 of the supporting member H and comprises a lower cylindrical section 3 open at its top and which has threaded in its upper portion the lower or bottom portion of a second or up,- per cylindrical member 4. rlhis member 4 is also open at its top.

The bottom wall 5 of the upper member 4 plan of the has disposed therethrough a central openingv 6 continued by a` depending tube 7 terminating, when the members 3 and 4 are in 'assembled relation, ata pointsubstantially central oi' the member 3.

The opening 6 is also continued by an up bottom wall 5 of the member 4 is a spring.

12 providing( a resilient rest tor the applied magazinemember 11. The magazine member 11 is provided with a plurality ot pockets or cavities 14 open at the top of the member 11, each of which being adapted,

to contain a tumigating material, material in one of said pockets or cavities preferably differingirom that in the others. Rotatably mounted on the top or". the member 11 is a plate 15 provided with openings 16 adapted to register with the outer or open ends oi' the pockets or cavities 14 whereby an ei't'ectivc'nieans'is provided vto regulate the fumes discharged trom such pockets or cavities 14.

The member 11 is provided therethrough with a central opening 17 permitting the member 11 to readily slide upon the tube 18 and the upper portion of this opening 17 is enlarged to provide a chamber 18 surrounding the upper portion of the tube S so that th-e fumes discharged from within the member 4 and as they pass out through the slots 9 may be permitted to min with the fumes discharged from the cavities or pockets 14.

The spring 12 operates to maintain the applied member 11 spaced from the bottom 5 ot the member 4 to permit a desired `fumigating material to be placed within tle lower portion of such member 4, the fumes of such material passing out through the opening 19 extending through the member 11. The plater 15 is also provided with an opening 2O for coaction'with the upper or outer end of the opening' 19.

The plate 15 may be rotated in any desired manner but, as herein disclosed, the peripheral portion thereof is provided with an outstanding knob v21.

The fumigating materials placed within the members 3 and 4 or within the various pockets or cavities let may be of any preferred constituency, .such as insecticides, rust eliminating, etc.

F rom the foregoing description it is thought to be obvious that a fumigator constructed in accordance with my invention is particularly well adapted for use by reason of the convenience and facility with which it may be assembled and operated, and it will also be obvious that my invention is susceptible of some change and modification Wit-hout departing from the principles and spirit thereof and for this reason I do not wish to be understood as limiting myself to the precise arrangement and formation of the several parts herein shown in carrying out my invention in practice except as hereinafter claimed.

I claim 1. A fumigator comprising a lower container, a hollow cylindrical member closing the upper end thereof and having therein a central tube, said tube being extended through the base of said cylindrical member to enter the lower container, an upper container slidably mounted in the cylinder, spring means housed in the cylinder for normally retaining the upper container in an elevated position in the cylinder, said tube being provided at its upper end wit-h slots7 a screw threaded in the upper end of the tube and adapted to overlap the slots, said upper container having a central cavity which receives the slotted portion of the tube and with its wall surfaces spaced therefrom.

2. A fumigator comprising a lower container, a hollow cylinder closing the upper end of the lower container, an upper container slidably mounted in the cylinder, spring means interposed between the bottom of the cylinder and the upper container for normally holdingl the samein an elevated position in the cylinder, said upper container having a passage-way leading from the top end thereof into the space between the upper container and the bottom of the cylinder, said cylinder having a central tube, said tubeextending in opposite directions and entering both containers, the upper portion of the tube being slotted, a movable member carried by the tube and adapted to overlap the slots, the upper container having a r socket which receives the slot-ted portion of the tube and with the wall surface thereof spaced from the surface of the tube.

In testimony whereof l hereunto affix my signature.
